Online Port Scanner IPv6

The Online Port Scanner allows you to scan a host or IPv6 address for an open or closed TCP port. If a response is received from the given host/IP on the specified port within 8 seconds after scanning, a confirmation will appear. This is a great online scanning utility to check if an IP, host or service can be reached from the internet and especially if the TCP port is open or closed.

Note: IPv6 support is currently limited to IP notation only, unless the host is reachable only through IPv6. Resolution of multi stack (IPv4 and IPv6) DNS names to IPv6 is under development!
